| Feature | Planwright | Linear | Plane | Writbase | GitHub Issues + Copilot |
|---|---|---|---|---|---|
Native MCP server GitHub has community MCP servers; no official first-party MCP for Issues. | |||||
Agent as first-class user Copilot agents can create PRs but can't manage Issues lifecycle natively. | |||||
Acceptance-gate workflow Planwright enforces scheduled → in_progress → acceptance → done. Agents cannot mark work as done without human review. No other tracker enforces this state machine. | |||||
Signed audit chain Planwright: hash-chained, ECDSA P-256 signed via AWS KMS, independently verifiable. Writbase has an append-only event log but no cryptographic signing or public verification. Linear and Plane have activity logs but not hash-chained. | |||||
Public trust page Planwright publishes chain integrity, record count, and the signing public key at /trust/{workspace} — no auth required. Auditors can verify independently. | |||||
SOC 2 evidence export Planwright exports a signed JSON bundle with full audit chain and verification instructions. Plane has SOC 2 Type II certification but doesn't export a customer-specific signed artifact. | |||||
SOC 2 / ISO 27001 certified Plane has SOC 2 + ISO 27001 today. Planwright's SOC 2 Type I is on the Phase 3 roadmap. GitHub (Microsoft) is broadly certified. | |||||
SSO (SAML / OIDC) Planwright SSO is on the Phase 3 Enterprise roadmap. | |||||
Self-hosted / on-prem option Plane and Writbase (Apache 2.0) can self-host. Planwright self-hosted is Phase 3. GitHub Enterprise Server is available for on-prem. | |||||
Open source Plane is open-core (AGPL). Writbase is Apache 2.0. Planwright is SaaS-only today. | |||||
Free tier | |||||
Agents count as billable seats None of the major trackers count agents as seats. Pricing is per human. |
claim_objective andrequest_acceptancewere designed for an agent's mental model, not wrapped from a human API.If your compliance team needs cryptographic proof that a human reviewed every agent-generated change, Planwright is the only option that ships it as a core primitive.
